Hi! _Finally_ my ISP has started to provide IPv6 support, and hands out delegation prefixes in what seems to be a proper fashion. My router is a PCengine with 3 ethernet interfaces running NetBSD 10.0-REL.
Interface wm0 connects to the ISP. Interfaces wm1 is an internal "house network". I use dhcpcd to obtain IPv4 and IPv6 addresses from the ISP. This works fine. I also try to obtain an IPv6 prefix delegation. This also seems to work fine. What _doesn't_ work fine, is actually delegating (parts of) the obtained prefix to an internal interface. I get the following error in syslog: dhcpcd[5044]: wm0: cannot delegate to vm1: Device not configured But the device _is_ configured. I use "static ip_address=" in dhcpcd.conf and the log says dhcpcd happily assigns the address to wm1, so it _is_ $configured, for some value thereof, but obviously not the correct value. I've tried to follow https://www.netbsd.org/docs/guide/en/chap-net-practice.html#chap-net-practice-pppoe-ipv6pd and one thing I've noted is that on NetBSD 10.0 ... # sysctl -w net.inet6.ip6.accept_rtadv=1 sysctl: fourth level name 'accept_rtadv' in 'net.inet6.ip6.accept_rtadv' is invalid but then again, I _do_ get an IPv6 address for the external interface (with dhcpcd running), so I believe that that it not part of the problem. And I also do get a prefix (/56) from the ISP for delegation. It's just that dhcpcd doesn't want to play ball and hand it to wm1, probably because of my ineptitude. All hints will be warmly appreciated.
